Hello Guys,

I am working on a Problem that is as follows:

There is a cylindrical chamber in which some volatile compund being injected from inlet and there is wall inside of this chamber that is made of some material on which I need to simulate Adsorption and Desorption of this volatile compund.

Till this material continues adsorbing VOC compound or act as a sink, injecting VOC continues and once it reaches to Equilibrium when there is no Desorption and Adsorption or it does not act as source or sink,we stop injecting VOC and inject fresh air.So Desorption starts from wall.

And this condition I have to defined as user defined function on this wall material surface as boundary condition.

This whole procedure I need to do in Ansys Fluent.So if somebody has any idea about how to initiate and proceed for this Problem,Please share your ideas.

Thanks for Suggestions ...
